    Epidemiological comments Within the framework of the epidemiological surveillance of avian influenza in Cameroon, Veterinary services from the Extreme North region notified an important mortality of peacocks in an exotic poultry farm located in the Makilingaye township, Tokombéré district, Mayo-Sava department, close to the border with Nigeria. Samples were taken and analyzed by the National veterinary laboratory (LAVANET) of Garoua. H5 serotype was confirmed on January 16th, 2017 and H5N8 on January 19th, 2017. Provisional measures were taken according to Law 006 of 16 April 2001 on animal health standards applying to livestock diseases legally considered as contagious and notifiable and according to the OIE Terrestrial Animal Health Code. Three-kilometers protection zones and ten-kilometers surveillance zones were established and the appropriate control measures were implemented accordingly. The samples were sent to an international reference laboratory. According to the Director General’s letter from December 26th, 2016, any case of highly pathogenic avian influenza in birds other than poultry, including wild birds, detected from January 1st, 2017, is notified to the OIE through WAHIS under the new disease name: Highly pathogenic influenza A viruses (infection with) (non-poultry including wild birds).

    Cameroon: Three new avian influenza outbreaks in northern Cameroon

    By Elodie N. BODOLO | Cameroon-Info.Net
    YAOUNDE - 20-Feb-2017 - 14:58 645 1

    After the central, southern and western regions, the northern region is threatened by avian influenza. According to the EcoMatin newspaper in its edition of Monday, February 20, 2017, the news would be part of the World Health Organization (WHO) which made public a document related to it. The document states, however, that the virus involved this time has nothing to do with the H5N1 virus, responsible for the last epizootic on the national triangle.

    Indeed, it is recalled that in June 2016, outbreaks of avian influenza due to the H5N1 virus had been discovered in the main cities of the regions mentioned above namely Yaoundé, Bafoussam and Ebolowa. A situation that for more than two months had paralyzed the poultry farming sector which still pays the costs today according to Joseph Wette, breeder. According to him, it remains difficult to get out in the sector because of the big loss of profit caused by the cessation of its activities a few months ago.
